Protective composite wrap

Abstract

A process of making a protective composite wrap, which exhibits the ability to protect metallic objects from corrosion environments, wherein a first thermoplastic resin and a vapor corrosion inhibitor are blended into a homogenous blend, wherein the homogenous blend is extruded into continuous thermoplastic filaments, which are collected into a nonwoven fabric, wherein a second thermoplastic resin is extruded into a continuous thin film, and wherein the nonwoven fabric and the thin film are affixed into a face to face juxtaposition to form the protective composite wrap.

What is claimed is:  
     
         1 . A process of making a protective composite wrap, comprising: 
 a. providing a thermoplastic resin;    b. providing a vapor corrosion inhibitor;    c. blending said thermoplastic resin and said vapor corrosion inhibitor into a homogeneous blend;    d. extrude said homogeneous blend as continuous thermoplastic filaments;    e. collecting and consolidating said thermoplastic filaments into a nonwoven fabric; and    f. said nonwoven fabric exhibiting the ability to protect metallic objects from corrosion environments.    
     
     
         2 . A process of making a protective composite wrap as in  claim 1 , wherein said thermoplastic resin is selected from the group consisting of polyamides, polyester, polyolefins, and the combinations thereof.  
     
     
         3 . A process of making a protective composite wrap as in  claim 2 , wherein said polyolefin is polypropylene.  
     
     
         4 . A process of making a protective composite wrap as in  claim 1 , wherein said is a morpholinic compound.  
     
     
         5 . A process of making a protective composite wrap as in  claim 4 , wherein said morpholinic compound is bis-morpholine, 4,4′-(oxydi-2, 1-ethanediyl).  
     
     
         6 . A process of making a protective composite wrap as in  claim 1 , wherein said continuous filaments are cut to a finite staple lengths.  
     
     
         7 . A process of making a protective composite wrap as in  claim 1 , wherein said consolidating means is a thermal calendaring process.  
     
     
         8 . A process of making a protective composite wrap, comprising: 
 a. providing a first thermoplastic resin;    b. providing a second thermoplastic resin;    c. providing a vapor corrosion inhibitor;    d. blending said first thermoplastic resin and said vapor corrosion inhibitor into a homogeneous blend;    e. extrude said homogeneous blend as continuous thermoplastic filaments;    f. collecting and consolidating said thermoplastic filaments into a nonwoven fabric;    g. extrude said second thermoplastic resin into a continuous thin film;    h. affix said nonwoven fabric and said continuous thin film into a face to face juxtaposition to form a protective composite wrap; and    i. said protective composite wrap exhibiting the ability to protect metallic objects from corrosion environments.    
     
     
         9 . A process of making a protective composite wrap as in  claim 8 , wherein said second thermoplastic resin may be selected from a group of polyamides, polyesters, polyolefins, and combinations thereof.  
     
     
         10 . A process of making a protective composite wrap as in  claim 9 , wherein said second thermoplastic resin is polyethylene.  
     
     
         11 . A process of making a protective composite wrap as in  claim 8 , wherein said first thermoplastic resin is different then said second thermoplastic resin.  
     
     
         12 . A process of making a protective composite wrap as in  claim 8 , wherein said continuous thin film is extruded directly upon the nonwoven fabric.  
     
     
         13 . A protective composite wrap comprising a nonwoven fabric comprised of a thermoplastic resin and a vapor corrosion inhibitor present at a let down value of about 0.8% by weight, said nonwoven fabric having affixed thereto a continuous thin film to form a protective composite wrap, said protective composite wrap capable of protecting a metallic object from a corrosion environment in accordance with ASTM B-117 whereby said protective wrap is capable of protecting said metallic object at a maximum level of oxidation of no greater than 0.3% at a maximum time interval of 21 days.  
     
     
         14 . A protective composite wrap as in  claim 13 , wherein said material is used in the fabrication of steel wrap.
